Intimate Strangers

We are crowded in an elevator facing a metal door, we stand behind each other with baskets in a check out line, we sit in a crowded doctor's waiting area, we stand with baggage through security lines... waiting... spending moments or hours together but politely isolated... who are these people I have spent so much time with... who are those taken off balance by a smile and suspicious if a comment is made.. who clutch their bag more tightly if a movement accidentally places us too close... I suppose I will have to wait to know..
